When you guys use the Manual Aux Control (F5) to adjust your AFR doesn't it work accurately?
Just as an example:
I will 14.7 Commanded and see 14.7 on the WB. Because it was tuned that way.
I adjust the manual AFR to command 13.8 with one click. 14.0 will show up on the wideband. I click one more time for 12.8. The WB will show something like 13.2 or 13.3.
In other words the PCM always underadjusts or the adjustment are always flawed. Is this how it is in reality?
Thank you.
